Definitions

  • This application relates generally to warewashers such as those used in commercial applications such as cafeterias and restaurants and, more particularly, to an idling system for such warewashers.
  • warewashers commonly include a housing area which defines washing and rinsing zones for dishes, pots pans and other wares.
  • wares are moved through multiple different spray zones within the housing for cleaning (e.g., pre-wash, wash, post-wash (aka power rinse) and rinse zones).
  • One or more of the zones include a tank in which liquid to be sprayed on wares is heated in order to achieve desired cleaning. Maintaining the water at the desired temperature is important for machine operation. Due to water movement within the tank, the temperature within the tank can be maintained relatively uniform when a spray recirculation pump is operating for spraying wares within the zone. However, when the machine is idling and/or the pump is not otherwise being used for spraying, the lack of water movement results in uneven water heating.
  • a warewash machine includes a chamber for receiving wares, the chamber having at least one spray zone. Both a primary recirculation system for delivering liquid from a tank to a spray system, and a secondary recirculation system for stirring or mixing liquid within the tank without passage of the liquid through the spray system are provided.
  • the secondary recirculation system may be operated during machine idling as needed to maintain desired tank temperatures, while flow through the primary recirculation system is maintained off.
  • a warewash machine in another aspect, includes a chamber for receiving wares, the chamber having at least one spray zone, and a a spray system in the spray zone for spraying liquid onto wares for cleaning.
  • a tank captures sprayed liquid that falls within the spray zone.
  • the tank includes a primary recirculation path for delivering liquid from the tank to the spray system, and a secondary recirculation path for delivering water out of the tank and back into the tank, without spraying within the spray zone, in order promote mixing within the tank.
  • a warewash machine includes a chamber for receiving wares to be cleaned, the chamber having at least one spray zone and a liquid collection tank.
  • a primary recirculation system delivers liquid from the collection tank to a spray system for spraying liquid in the spray zone.
  • a secondary recirculation system is provided for mixing liquid within the tank without passage of the liquid through the spray system.

Either continuously or intermittently moving conveyor mechanisms or combinations thereof may be used, depending, for example, on the style, model and size of the warewash system 10. Flight- type conveyors in which racks are not used are also possible.
  • the racks 12 of soiled wares 14 enter the warewash system 10 through a flexible curtain 22 into a pre-wash chamber or zone 24 where sprays of liquid from upper and lower pre-wash manifolds 26 and 28 above and below the racks, respectively, function to flush heavier soil from the wares.
  • the liquid for this purpose comes from a tank 30 and is delivered to the manifolds via a pump 32 and supply conduit 34.
  • a drain structure 36 provides a single location where liquid is pumped from the tank 30 using the pump 32. Via the same drain structure, liquid can also be drained from the tank and out of the machine via drain path 37, for example, for a tank cleaning operation.
  • wares are subject to sprays of cleansing wash liquid (e.g., typically water with detergent) from upper and lower wash manifolds 42 and 44 with spray nozzles 47 and 49, respectively, these sprays being supplied through a supply conduit 46 by a pump 48, which draws from a main tank 50.
  • a heater 58 such as an electrical immersion heater provided with suitable thermostatic controls (not shown), maintains the temperature of the cleansing liquid in the tank 50 at a suitable level.
  • a device for adding a cleansing detergent to the liquid in tank 50 is During normal operation, pumps 32 and 48 are continuously driven, usually by separate motors, once the warewash system 10 is started for a period of time.
  • the warewash system 10 may optionally include a power rinse (also known as post-wash) chamber or zone (not shown) that is substantially identical to main wash chamber 40.
  • a power rinse also known as post-wash
  • racks of wares proceed from the wash chamber 40 into the power rinse chamber, within which heated rinse water is sprayed onto the wares from upper and lower manifolds.
  • the final rinse chamber 54 is provided with upper and lower spray heads 56, 57 that are supplied with a flow of fresh hot water via pipe 62 running from a hot water booster 70 under the control of a solenoid valve 60 (or alternatively any other suitable valve capable of automatic control).
  • a rack detector 64 may be actuated when a rack 12 of wares 14 is positioned in the final rinse chamber 54 and through suitable electrical controls (e.g., the controller mentioned below), the detector causes actuation of the solenoid valve 60 to open and admit the hot rinse water to the spray heads 56, 57.
  • the water then drains from the wares and is directed into the tank 50 by gravity flow.
  • the rinsed rack 12 of wares 14 then exits the final rinse chamber 54 through curtain 66, moving into dryer unit 18, before exiting the outlet end 17 of the machine.
  • An exhaust system 80 for hot moist air may be provided.
  • a cold water input may be provided.
  • waste heat recovery unit (not shown) to recover heat from the exhaust air.
  • Other heat recovery components may also be employed.

  • tank level sensors LI and L2 e.g., float switches or electrical impedance sensors
  • machine tank 50 is referenced, it is recognized that other tanks of a machine could include similar secondary recirculation arrangements.
  • the heating element 58 switches ON when a lower temperature set point of liquid in the tank 50 is reached (as indicated by temperature sensor Tl) and switches OFF when an upper temperature set point is reached (as indicated by temperature sensor T2). In addition, the heating element 58 only switches ON if the liquid is above a set lower level (as indicated by level sensor LI) and remains OFF when the liquid is below the set lower level (as indicated by level sensor LI).
  • Operation of the secondary recirculation pump 100 may be tied to the heating element controls. Control of the secondary recirculation pump 100 may be according to the lower and upper temperature set points in the tank, as well as the low level setting to protect the pump.
  • the various temperatures corresponding to the lower and upper tank set temperature points, chamber temperature (as indicated by temperature sensor Tl) and the tank fluid temperature (per sensor T2) may be used to control the secondary recirculation pump 100.
  • the lower and upper tank set points temperatures which control the heating element 58 may simultaneously control the secondary recirculation pump 100.
  • the heating element 58 turns ON when the tank liquid temperature falls to lower temperature set point and switches OFF when the liquid temperature rises to the upper temperature set point.
  • the secondary recirculation pump 100 may turn ON simultaneous with the heating element 58 to ensure uniform mixing of the tank liquid until the upper temperature set point is reached, at which point both the heating element 58 and secondary recirculation pump 100 switch OFF

  • Equation (1) can activate both the secondary recirculation pump 100 and the heating element 58 to position the machine ready for washing. Also, Equation (1) can activate the secondary recirculation pump 100 without activating the heating source 58 until the tank liquid temperature drops to the lower set point and/or the chamber temperature activates the heating element 58. Notably, in such idling operations the major spray pump 48 need not be operated at all.

  • the term controller is intended to broadly encompass any circuit (e.g., solid state, application specific integrated circuit (ASIC), an electronic circuit, a combinational logic circuit, a field programmable gate array (FPGA)), processor (e.g., shared, dedicated, or group - including hardware or software that executes code) or other component, or a combination of some or all of the above, that carries out the control functions of the machine or the control functions of any component thereof.
  • the controller may include variable adjustment functionality that enables, for example, the upper and lower temperature set points to be varied and/or Equation (1) to be modified (e.g., via an operator/user interface associated with the controller 200 or via a restricted service/maintenance personnel interface).
  • Fig. 3 shows an exemplary process algorithm based on Equation (1) and the tank temperature set points for activating the secondary recirculation pump 100 and heating element 58.
  • the chamber air temperature sensor Tl and tank temperature sensor T2 are checked at 300.
